Installed QT 5.5.0 on Fedora22: Help me set required permission

SGaist

Hi and welcome to devnet,

Where do you get that error exactly ? What where you trying to do ?

nishu-tryinghard

I just opened qt 5 from the applications menu. So qt will be opened by the user but not root.
I wanted to have a look at inbuilt examples so i headed to examples tab and clicked on a example after which i got a notification saying i dont have write permission for /opt/qt5.5.0 .

SGaist

Go to the project panel and check the shadow build path. It's pointing to something like /opt/where_the_example_is_located/build-MyExample-Debug_etc. Change the path before build-MyExample-Debug-etc. to a place where you can write and you should be good to go

nishu-tryinghard

@SGaist Shadow build path is set to /home/user where it is writable. And i get "some_file.h no such directory or file" error if i run.

SGaist

Did you re-run qmake after changing the path ?

nishu-tryinghard

@SGaist Do i have to run qmake in terminal or is it a equivalent of build?

SGaist

You can do that from the Build menu.

No it's not the equivalent of a build, qmake is a project manager (like cmake, QBS etc.). It set things up for you so then you can do builds.

nishu-tryinghard

@SGaist Done, even after running qmake it gives the same error as before about missing header file.

SGaist

Which header is missing ?

nishu-tryinghard

@SGaist /home/nishanth/gallery/main.cpp:41: error: qtquickcontrolsapplication.h: No such file or directory

Dont you think all these issues are because of permission issues?

SGaist

No, it's not a permission problem. Seems like you moved some stuff around that find is in qtquickcontrols/examples/quick/controls/shared

nishu-tryinghard

@SGaist I didnt move anything i installed it a while ago so i didnt do any changes or moved anything.

SGaist

The path "/home/nishanth/gallery/main.cpp" doesn't look correct gallery should be in qtquickcontrols/examples/quick/controls/

nishu-tryinghard

@SGaist Ya i did explain why it is at /home/nishanth/.
When i select a example it gives a notification saying this [IMG]http://i62.tinypic.com/2h5u3p3.png[/IMG]
After which i makes a copy at /home/nishanth

SGaist

Ok, then you need to also copy the "shared" folder at the same place.

I though you only changed the shadow build path not copied the whole example

nishu-tryinghard

I really didnt get what to do can you please elaborate please.

SGaist

Copy the folder name "shared" that is in the example folder /quick/controls/ in /home/nishanth/

nishu-tryinghard

I had to copy the contents of shared folder "Examples/quick/control/shared" to the example folder in my home directory.
Here home directory is set as my project directory.
Ty very much for helping me.
But dont you think all these should work out of the box?

SGaist

AFAIC Qt Creator assumes that examples are self contained. These are a bit of a special case
